3.5. USB-TO-UART Interface (J0901/J0902)
The EVB provides a USB-TO-UART interface (J0901/J0902). This interface is used for Linux console and
converting debug log UART signal to USB 2.0 signal.
Before using the USB-TO-UART interface, DBG_RXD and DBG_TXD of the module should be connected
to the corresponding positions of J0902.2 (RXD_1V8) and J0902.3 (TXD_1V8) on the EVB respectively. A
connection example of RM500Q-GL module is shown as below.
